MOTQBrTBACTOR.

To all whom it may concern Be it known that I, GEORGE J. STOLL, a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Motor- Tractors, of which the following is a specification. i

The invention is primarily designed to utilize a motorvehicle as a tractor for haul.- ing vehicles of every dtscription as well as propelling agricultural implements over the reader field.

The invention has for its object the conversion of a motor vehicle-into atmctor and vice versa, whereby such vehicle may be utilized both as a tractor and carrier.

The invention contemplates anarra-ngenient whereby the rear or drive wheels of a motor Vehicle are ada iited to be replaced by gear wheels, such gear. wheels inturn being connected by suitable n'ieans with the wheels of a truck,*vehicle, or like device so as to impart movement thereto for propelling the vehicle, implement, or like contrivance, to be driven.

The invention further has for its object the provision of novel. connecting means between the motor' vehicle and the truck, or like part, whereby both-are adapted to have an "independent movement to allow for inequalities in the surface over which the tree tor and truck are moving as well as to admit of proper steering.

With these and other objects in view, which Will readilyappear as'the nature of the invention is better understood, the same consists in the improved construction and novel. arrangement and combination; of parts which will be hereinafter fully and particularly claimed.-

In the accompanying illustrated a simple and preferred form of the invention, it being, howeyr. understood that no limitation is necessarily made to the pmcise structural details therein exhibited, but that changes, alteratibns, and modificzn tions within" the scope/of the invention as claiu'ied may be resorted to when desired.

Referring to the drawings, Figure 1 is a view in elevation of a'inotor vehicle utilized as a tractor and/a wagon coupled thereto described 1 i.

and having its/"front wheels connected to: the rear or drive axle of the motor veh cle. Fig. 2 is an ,,e1ilarged sectional vlew ofthe '1 drawings has been sp m of Letters Patentedil'an. 16, 1.917.

rear portion of the motor vehicle and the truck. coupled thereto. Fig. 3 is a top plan view of the parts illustrated in Fig. 2, the body of the motor vehicle being omitted to show more clearly the connecting means be tween the truck and frame of the tractor and between the wheels of the truck and the rear axle of the tractor. Fig. -i is a trans verse section, on the line 4:"4: of Fig. 5. Fig. 5 is an enlarged view showing the means for connecting the spring joining the truck and tractor to the frame of the motor vehicle. Fig. 6 is an enlarged section. on the line (3--'-6 of Fig. 2 showing the means connecting the front end of the side spring to the frame of the motor vehicle.

Corresponding and like parts are referred to in the following; description and indicated in all the views of tl'iedrawings by the same reference characters.

Ilic numeral 1 d gnates a motor vehicle of any umlie or t gn and 2 a, wagon or The motor vehicle may be driven by means of a motor 01'' any type Land oompi' a frame 3, rear axle 4 and usual parts essential to the proper open ation of a motor driven vehicle. The rear axle i is adapted to be connected to thebod y of the vehicle in any" well known manner and coupled to the motor, not shown, so as to receive motion therefrmn. The axle 4: is mounted in a housing 5 which is provided at its outer ends with drums 6 for lIlClOSlIlg my well known type of brake mechanism. l Vhen the ureter vehicle converted into a tractor the usual rear wheels,uot shown, are

removed and are replaced by means of gear wheels 7 which may be oil any diameter depending upon the power and speed required.

The gear wheels 7 are secured, to the outer ends of the axle 4- so as to rotate therewith and are adapted to be readily replaced by gear wheels of different size, tl'uireby adaptin the motor Vehicle, when used as a tractor, for the na 1i.'6 of work IGqlll red.

Longitiulinal springs 8 are disposed at the sides of thombtor vehicle and are iizonnected tllvf' 'i') afttheiri'orward ends and intcrinci'liatefl'of their en.

The forward end of the spring is connected to a bracket 13, which is attached at one end to the side bar 3 and has its opposite endprojecting laterally beyond the side bar and terminating in a sleeve through which a pin 14 is passed"; Shackles 15 are connected at their lower ends to the bracket 13 by means of the pin 14 and a pin 16 .connects the upper ends of the shackles to an eye formed at the front end of the spring 8. The bracket 13 is adapted to be secured to the side bar 3 in any manner. The rear end of each of the springs 8 is adapted to be attached to the truck or other part to be drawn inany convenient and substantial way. As indicated a clip 17 is attached to the axle 18 of the truck, vehicle, or like part and the spring 8 is attached to such clip in any preferred way. i

The vehicle 2 is provided with a foretruck which is connected thereto so as to turn about a vertical axis, such connection including the ordinary fifth wheel. The upper member of -the fifth wheel is connected to the body or sub-structure of the vehicle, whereas the lower member of the fifth wheel is attached to the fore-truck: The truck comprises longitudinal bars 19 and cross bars 20. The lower member 21 of the fifth wheel is mounted upon the cross bars 20 and is secured thereto in any way. Side springs 22 connect opposite ends of the longitudinal bars 19 and such springs in turn are attached midway of their ends to the axle 18. The wheels 23 mounted upon the arms of the axle 18 are provided with gear wheels 24: which are connected to the gear wheels 7. by

means of drive chains 25. It is to be understood that the gear wheels 24 may be of any diameter.- The wheels 23 are adapted to be driven in substantially the same manner -as the usual. drive wheels of the motor vehicle, hence provision is had for making turns.

To reserve an approximate uniform distance tween the centers of the .axles 4 and 1 8 to finsure pro er transmission of the power by means 0 t drive chains 25. suitable corn ecting meaiis are interposed be truck. Such connecting means-is preferably adjustable whereby provision is had for coupling the tractor to different vehicles and also to allow for substitution of drive gears I and 2a of different diameters. As

tractor and truck, each of such parts embodying members 26 and 27. The member 26 consists of a short bar which is 'fastened 29 connect the rear part of the frame 3 with the front part of the truck of the vehicle 2 or like part.

From the foregoing taken "in connection with the accompanying drawings it will be understood that the invention provides for the utilization of a motor vehicle, both as a tractor and carrier, the parts associated therewith admitting of the ready conversion of the vehicle from one use to the other.

'70 shown the means embody'sinnlar parts,

which are disposed at the sides of the The truck when coupled to the motor vehicle admits of the ready adaptation of the invention as a tractor to a vehicle of any type or to an agricultural implement for drawing the same over the road or field. The provision of the gear wheels and the adjustable connection between the frames of the motor vehicle and truck provide for the ready adaptation of the invention to loads of different mass, thereby preventing the overtaxing of the motor vehicle.

An essential feature of the {invention is the provision whereby the gear wheels 7 may be quickly removed and replaced by Others of different size so as to adapt the tractor I to the load and required speedy It is further noted that the connection 29 between the fore-truck and themotor vehicle should be of a nature to allow for independent I movement. of "the vehicle and truck, "hence sue connection is provided in its length with a coil. It is to be understood that a flexible connectionof any kind maybe substituted for the connection 29 Having thus described the invention what I i claimed as new is In combination, a motor vehicle, a truck, bowed springs connected to the forward axle of the truck and extending along .op osite sides of the motor vehicle, means at t e intermediate. portion of each spring detachably securing the same to the respective side of the rear end of the motor vehicle, means at the forward end' of each spring detachably securing the same .to the respective side mentioned securing means, the-said sprin s -of the motor vehicle in advance of the fir.
